ABSTRACT:
Disclosed are electrorheological fluids having ceramic particles of high ion conductivity and a nonconducting or dielectric fluid. The high ion conductive particle may be a material having the formula A.sub.5 MSi.sub.4 O.sub.12, where A is a monovalent ion, such as a material comprising at least one selected from the group consisting of Li, Na, and Ag; and M is a trivalent ion, such as a material comprising at least one selected from the group consisting of Sc, Fe, Y, In, La, Ce, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu. The liquid phase may include a silicone fluid or mineral oil. In the case of a mineral oil, the oil may also include an amine-terminated polyester to improve stability of the fluid.
